How can you write that 6D has equal image quality than D600 when 6D paired to its best lens, the sigma 85mm f/1.4, has a overall score of 34, and D600 scores 40 with its own 85mm f/1.8 (not even mentioning the nikkor 85mm f/1.4 wich is overprice and to stay below the best lense for canon)...

Please have a look at our title for this part : “Canon EOS 6D versus Nikon D600: IQ of D600 is slightly higher”, I think we agree For the first part, we tried to compare some lenses that should provide very close optical results on both systems. That is why we did not mention the Nikon 85mm but the Sigma 85 and 35mm.
